I'm trying to put together a slightly smaller testcase, but you can see the effect by uncommenting the override() test in Class::Modular (on cpan) and running make test; The corefile will be available at http://rzlab.ucr.edu/debian/<bugnum>/corefile as soon as I get an ack from the BTS.

It does not haggle over expenditures on armaments and military equipment. It pays without discussion, it ruins itself, and that is an excellent thing for the syndicates of financiers and manufacturers for whom patriotic terrors are an abundant source of gain. -- Anatole France http://www.donarmstrong.com http://rzlab.ucr.edu
